Lumatone mapping for 49edo
There are many conceivable ways to map 49edo onto the onto the Lumatone keyboard. Only one, however, agrees with the Standard Lumatone mapping for Pythagorean.
Diatonic
Cam Taylor demonstrates this mapping in 49-equal: 7-equal meets superpyth (2023).

Keep in mind that 49edo is a superpyth temperament, so 5/4 is mapped to the interval of an augmented second (e.g. a 5/4 above C is D♯).
Other mappings
If you want to access single step movements in a more intuitive way and slightly extend your range, the rotated 6L 1s mapping is probably the best compromise, although it puts octaves all over the place.
